Minogue clashes with 'X Factor' co-stars

Dannii Minogue is at war with her fellow X Factor judges, according to a report today.

The singer, who was recruited by Simon Cowell as part of an overhaul of the show, does not get along with Sharon Osbourne or Louis Walsh.

Tension between Sharon and Dannii developed when the TV personality started to feel upstaged by Minogue. Meanwhile, the 35-year-old has clashed with Louis Walsh over comments that he made about her sister Kylie.

A source told The Mirror: "Sharon is used to being Queen Bee but Dannii is not afraid to speak her mind. That has grated on Sharon's nerves. Dannii and Louis barely spoke since he slagged off Kylie. She's very prickly about her sister. That made things awkward."

Minogue's "mean" attitude towards some hopefuls has also caused arguments between the judges.

The insider added: "They crossed swords with her over her harsh comments to the contestants. She has left some of them in tears."
